Serial No. 487,125..

My invention relatesto a coin control device and more particularly to coin detectors for use 111 com control devlces.

coin detectors of this general class have heretofore been used. It has been found, however, that devices of this general type have not been adapted for use in small vending machines for the reason that the slight tilting or tipping of these machines renders the device inoperative due to the change of angle of the weight bar. It also has been found that a weight bar coin detector made to operate on the heavier coins is not sensitive enough to operate successfully with lighter coins, such as dimes. If made sensitive enough to operate with the lighter coins, much difficulty is experienced in adjusting it for use. with heavier coins.

It is, therefore, an object of my invention to provide a coin control device having a weight bar coin detector which is so arranged asto be unaffected by any tilting of the vending machine in which it is a part, thus rendering it useful in smaller vending machines.

It is a further object of my invention to provide a coin control device having a weight bar coin detector. which is adjustable to control the sensitivity of the weight bar, thus permitting the same device to be used in coin control vending machines which may be used at difierent times with coins of different denominations.

It is a further object of my invention to provide a coin control having a coin detector which. is so constructed as to permit necessary adjustments in the coin chutes; when the device is tobe used with coins of varying T denominations.

With these and other objects in view, my invention-consists in the construction, combination and arrangement of parts as will be hereinafter more fully described and as illustrated in the accompanying drawing, in

Fig.7 is a detailed View partially in cross section of the mounting on a vending machine. for thecoin control mechanism.

Similar reference numerals refer to simila parts throughout the several views.

Referring. more in detail to the drawing 8, 9 and 10 designate three of the side walls of a coin controlledvending machine (not shown completely). It is to be understood that such a vending machine may beof any particular type which has a delivery mechanism operated through a shaft 11. While any desired form of coin control lock may be used on a shaft such as the shaft 11, one

form of such lock being shown in the drawspring actuated pawl 17 cooperates with the ratchets 13 to prevent a backward rotation of the plate 12 and the shaft 11. The plate 12 has a pocket 18 for receiving a coin 19. When the coin 19 has been deposited in the pocket 18, the coin projects beyond the outer edge of the plate 12 and acts to raise the spring actuated locking dog 16 sufficiently to prevent its contact with the rib 15 of the plate 12.

Coins are in the plate 12 through an upper coin delivery chute 20, formed'between a cover 20 and a plate 27 and a side coin chute 21, having a weight bar coin detector 22 separating said side coin deliverychute from the lower coin delivery chute 28. Coins passing through thecoin chute 20, not deflected by delivered to the coin pocket 18 adjacent the mouth of the side coin chute 21, the said flange being inclined toward said sidecoin chute 21. Coins coming in contact with said flange, roll directly from said chute 20 to said side coin chute 21. In order to separate spurious coins or coins of improper denominations from the coins which are admitted into the lower coin chute 23, slug expelling chutes 24 and25, communicating with a slug outlet, are provided. The slug expelling chute 24 is placed directly beneath the upper coin chute 20 and communicates with the forward end of the side coin chute 21, while the slug expelling chute 25 connects with the opposite end; of the side coin chute 21. I Mounted on the cover 20a'of the upper coin chute 20, is a magnet 26' for detecting coins having a high content of material affected by magnetic action. I

All of the coin control mechanism is mounted on a plate 27, having four cars 28 at the four corners of the said plate, the cars 28 being provided with holes29 for'rece-iving pins 30, which are mounted on the sides 8 and 9 of the coin controlled vending machine, the holes 29 in the ears 28 being larger than the pins 30 so as to permit movement of the entire plate relative to the sides of the coin controlled vending machine; At the lower edge of the plate 27 there is secured a weight 32, which is so secured as to act-as a pendulum to maintainthe plate 27in a relatively constant position regardless of slight movements of the coin controlled vending machine.

The side coin chute 21 comprises a. plate or cover 33, having elongated slots 34 and 85 and a' weight bar adjusting screw 36. Also mounted on the cover 33 are two projections such as'the projection 37 for forming the support for the pivots on both ends of the weight bar 22. The'weight bar 22 is mounted on adjustable pivot points 38 and 39 and has a pro? jection 40 whichcontacts with the point of the adjusting screw 36 to regulate the amount of movement of the weight bar 22; A counter weight 41' is provided in order to-adjustthe weight bar 22 for coins of various weights.

The weight bar 22 is provided at each end with recesses, such as'the recess 42 shown in Fig. 4. Jewels 43 are placed in each of said recesses, and furnish seats for the points of the adjustable pivot members 38 and 39.

The side coin chute 21, maybe adjusted to compensate for the thickness of various coins by adjustment of the back plate 44 movable ating shaft 11.

coin slot 20, such a coin will roll into the side coin chute 21 and onto the weight bar 22, the weight bar 22 having been so adjusted that the coin of arproper denomination will tilt the weight bar at such a time as to drop the coin into the lower coin chute 23, which delivers the-coin to'the coin pocket 18 in the plate 12 of thecoin lock keyed to the oper- When the coin has'been '7 placed in the coin pocket 1810f the plate-12, and 'the shaft is rotated, the coin contacts with the spring actuated locking dog 16 and raises it so that the plate 12 is free to rotate with the shaft 11. This permits the operation of the delivery mechanism; of the coin 0on During the time trolled vending machine.

that theplate 12 is being rotated with the shaft 11, when the proper coin is in the pocket 18, the springactuated pawl 17 conprevents'a backward rotation of the shaft 11.

Assuming that a'coin containing a high percentage of material responsive to magnetic influence, such as an iron or steel slug, is

placed in the coin controlled vending machine and reaches the upper coin chute 20,

the magnet 26 tends to draw such a coin toward it and the coin is then deflected into the,

slug expelling chute 24 and drops through this chute and out of the machine.

If a coin which is of too heavy a weight is placed in the machine, the coin will drop through the upper coin chute 20 and into the side coin chute 21, but its weight will be 'such' as to tilt the weight bar 22 as soon as the coin reaches the forward end thereof. This drops such a coin into the projection on the coin chute 24 and such a coin is conducted through the slug expelling chute machinev p i I v If acoin which is too light has been placed in the machine, it will drop through the upper coin chute 20 into the sidecoin chute 21, v

24 and out "of the but isnot of a sufficient weight to tilt the weight bar 22 and rolls beyond the lower end of the weight bar 22 and into the slugexpelling chute 25, through which it is taken out of the machine. I I

It will be apparent from the foregoing that the efficiency of the coin detection mechanism which Ihave employed in my coin control device, will be greatly-impaired by a change of the'inchnation of the side coin chute 21 and the weight bar 22. In order to compen-- sate for the usual tilting of the coin controlled vending machine, and in order to maintain the side coin chute 21- and the weight bar 22 at the predetermined angle relative tothe side of the coin controlled vending machine, the

plate 27 is supported by the operating shaft 11, but is free to rotate around said shaft and said shaft may be rotated without'afl'ecti'ng the said plate 27. The plate 27, being loosely mounted on the projections 31 and; the pins 30 on the sides of the coin controlled vending tacts with the ratchets 13 on the plate 12 and 5 T 9 Patent of the United States, is

50: and will tilt also on contact at the otherend machine, and being free to rotate around the shaft 11, is maintained in a relatively constant position due to the action of the weight 32 acting as a pendulum and tending to restore the plate 27 to its originalposition' regardless of momentary displacement due to tilting of the vending machine.

In order to provide one coin control which may be adjustable to take various sizes of coins, the slots 34: and 35 in the cover 33 of the side coin chute 21 permit the adjustment of the pitch or inclination of the coin chute 21 and the weight bar 22. The weight bar 22 may be adjusted to act on coins of different weights by an adjustment of the counter weight i1. The adjusting screw 86, acting on the projection 40 of the weight bar 22, may be adjusted to control the extent to which the Weight bar 22 is permitted to pivot to drop any particular coin. To provide for coins of various thicknesses the adjustable plate 14, at the rear of the coin chute 21, may be so adjusted that the projection 46 will leave sufficient space between the cover 33 of the side coin chute 21 to permit the passage of a thin coin, such as a dime, or it may be Withdrawn so as to provide a wider passage to permit the passage of thicker coins, such as twenty-five cent pieces.

While I have illustrated a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details of construction set forth, but desire to avail myself of all changes within the scope of the appended claims.
